Integrated / Course Elective: Public Projections
Fridays 13:00 - 16:00, HIT H12
Learn 3D, can be counted as course elective too!
Keywords: Perspective Illusions, 3D Modeling / Rendering, Blender 3D, Percent for Art (Kunst am Bau), Baden Stadtfest, VFX, Urban Scale Interaction/Animations
In the course you will learn about the key concepts of projection mapping and the open source software “Blender 3D”. You will produce animations that intend to alter the perceiption of a building’s facade or interact with the facade in a funny/graphical/informative way.
“Percent for art” / “Kunst am Bau” usually refers to art funded with a small percentage of large development projects. In case you decide to elaborate the designs of this course as a thesis elective, you will have the unique opportunity to perform your projections to a large audience at Stadtfest Baden (+/-one million people in one week in August 2012).
Using Blender you can either dig in deeper in what you already know about 3D visualization or use this opportunity to learn how to model and render in 3D from an animation point of view. This should be easily adoptable to your own projects and/or favourite 3D render software.
Supervision: Lukas Treyer
In december 2011 a group of students showed a few projections as a part of their thesis electives. The goal was to influence the perceiption of the facade above the bistro.
Podcast, Feb 24th 2012
Podcast of the introductory presentation of the course and the site in Baden.
A few links to start with modelling, animating and rendering in Blender. Main links: http://www.blender.org/education-help/tutorials/, http://www.blenderguru.com/, http://cgcookie.com/blender/
Deadline: March 8th, 12:00
Read pages 9 to 29 in the Precision Modelling Tutorial.
Hand in two models and a description.
Deadline: March 12th, 12:00
Try to come up with an animation similar to stuffmatic's Blob Study.
~10-30sec/250-750 frames. Render 10 to 30 frames (1 frame / sec) to get familiar with the render settings.
Deadline: March 29th, 12:00
Do one Cycles and one Blender internal renderer tutorial, if you haven't done so.
Hand in a few pictures of your (current) projection idea and share some notes about it in a text file.
With the help of drivers we can manipulate attributes of objects with python expressions (among others). Accessing any object\'s attribute by python enables us to link attributes between different objects, [...]
Choose between a) and b)
a) Try "something parametric" you might use in your design course or for the projection itself. Use Blender\'s "Driver" feature to accomplish this task. Drivers are [...]
At christmas 2010 and 2011 students of ETH used projections to illuminate the piazza at ETH Zurich Campus Hönggerberg. With spacial illusions it is important to know that the illusion usually works only for one view point. Due to our shifted camera method and Blender's "driver" feature (simplified python scripts) we are now able to animate the view point as well.
In this post all templates for the projections in Baden are being assembled. To start with a file containing the setup for the final presentation of the semester on a model, later on some setups for real scale projections.
Script that allows you to project your camera view onto a plane. What your camera see is being reproduced with vertices and lines - ready for exporting. 2D-Projection.blend.zip
In August 2012 students presented the "Public Projections" they did for their thesis electives. The projections were shown at Stadtfest Baden together with the works of projection artists. Cooperation between ETH Zürich, Information Architecture and Stadtfest Baden.
